justment of the rolls toward and from the common axis about which they are grouped; to; give ,to the rolls .an initial obhquity or angularity to said axis variable as required; to cause the degree of such obliquity to be changed-automatically in proportion to the drawing-together or spreading apart of the rolls, sothat the rate of feed shall be made 'tosuitthe work in hand; and generally to strengthen, simplify, and render convenient .the apparatus as a whole. ..The mechanism here shown and described maybeused at either or both ends of majchinerysuch as mentioned,but is ordinarily {used at-both ends, with no substantial difi'crence between the two. sets. The description of one will therefore answer for both, with ,mention of the slight variation in bearings found e edient in practice.

This will beseen in Fig; 6, where the periphery of the head M is shown provided with a series o'fholes or-socketst to receive the end of alpin u, which -is assed through holes a in the'clrcumferentia wall of the housing G.

The cams are of like efomr and earlike relationto' the common 'axiit hence If the cam-ringbe turned in idirectienl'to' bring the portion of shorter pasaedtliroug bosses formed on the upper to1bear-- on' opposite sides of a lug erringto Figs. ,5, 6, 8,9 and 10, it will ass . support to the noae eea' boxes and rolls fwillsbe simultaneously and equall movedunward; and .iftheYring-be' turne intherev'ersedirectiori Zthe-.boxes and rolls will 1 be 1 permitted to lrnoveioutwai'dr The u'pper'roll and itslonriialsbox'es require to .be moved positive y outward hbecause gfavitytends to move themdnward, hence t e uppermo'st cam 31 of eaclr-ring L=.is formed with alprojecting-ribw of'uniform width "or thickness and vpai'allelinwith. the face of the cam, and. the upper..,'ourn'al-box K is furnishediwith a hangerate: a, the laterally bent upper end of whi'c overhangs the rib s, as shown inFi 1,8,4 and 5,-andi causes the upper journa -box'-.to-lmove"out{ ward as the mug is turnedtobring the.portioirof the cam of-greaterr'adius over said. boxi The sprin 11 give a slightl .yieldin xesfand ltheir rro ls, l whic prevents injury to the rolls ili-the..event that; any excesslve irregularity-of the shaftingI enter between them. a v

The cam-rings are retained in position; and kept concentric with the housings F, G. by forward or outward extensions b :ofrthe housings, curved to -fit accurately-thecirs. cnmference of said rings, and by: retaining plates'c, bolted thereto, as seen iir 1Figs;.=8, 4 and 5. Thetwo housingsare' braced or;

It is unimportant to -what extent). they be separated, mitthe work, but it is importantzthat they: be not permitted to-aplproach'closer than: they should because t ey might in such. event exert undue 'ressure upon andf'injurethe work. Accor ingly, I provide means: for accurately limiting the rotation of the cam-rings in the closm direction. This will be seen in Figs. 8' an 4, where the rings- L are shown provided with peripheral notches f to receive the tail or laterally hent end of a stop-block O, secured upon the periphery of the ringlbf a bolt 9', there bemg a series of bolt 0 es corresponding in number with the notches f, so that b removin the bolt the tail or endofthe lock 0 can e set in any notch and the block then secured by the bolt. The inturned'end of the blockdirectly receives the strain -or p'ressurewhen the block encounters a coactmg'stop h while the' bolt retains the'block in place. he stop It. is preferably; 0. thread ed stem or bolt screwed into one'oi thelu or extensions 5" and standing in thepa of tho blook.

I wilt is important in machinery of this character tobe able to control its various parts -or1'elements from a single point, and it is necessary to'move in or out simultaneously the journal-boxes at the two ends of the r0lls-H.-i-For the urpose of rotating the rings L to effect this movement I form in the periphery of. each a series oi gear teeth at, and arrange a rack-bar. P to mesh with the teeth of each, said rack-bars being actuatedb a suitable motor, as presently explains i Owing tothe reversed inclination of the guideways in' which the journal-boxes K move, the cams of'the two rings L are similarly reversed; hence, to produce like effects :the rings re uire to be turned in opposite directions an therefore the racks P are arranged to move simultaneously and equally in opposite directions. This is conveniently done by connecting the .racks to opposite ';ends of the horizontal member of a T- ishaped lever Q, fulcrumed at the meetingpoint of the horizontal'and vertical arms, as seen in Fig. 1. Connection is made between the-rack-bars P and the arms of lever Q, througlrthe medium of rods R, pin-ljointed tolthemack-bars,extending down tirou h iuides 7", and finally passing throu h bloc cs ivotally supported in i the. for red ends of e lever arms, asshown in Figs. 1 and '2invThe'lower ends of the rods R are screwlthr'eaded, and furnished with-nuts Z'- above and below the pivot-blocks, permitting either rack-bar to be uadjustedigher or ower with-reference to the other, so as to 'give' thef proper relative movements of the two rings L.-- 1 I 1T6 =facilitate'the initial set-tin of the Jflniiand racks, theracks-are hel in mesh wit the teeth of the rings by flanged rollers syoarried on one of the tie-rods which connectthe housings F, G. By slidin the flanged rollers on the tie-rod out of line with the rack-bars, :the rack-bars can be swung1 away from the rings, and permitting t e latter to be turned to proper position, after which the rack-bars are swung back to meshing position, and the rollers are restored to place.

' The lever Q has its upright member connected by a link or rod m with the pistonrod of a fluid-pressure motor '1, here represented as an ordinary double-acting steam engine with a slide valve U which can be set by a hand lever V to admit steam to either end of the cylinder at will, or to cut oil-steam therefrom, the valve being shown in its medial or'cutting-ofi position in Fi 1. 1 When the rolls are emplo ed for finishing shaiting I preferably ma to them of the contour best shown in Fig. 5, that is, with the lnfeedin end slifihtly tapering.
